Advantages of DR MagLevAdvantages of DR MagLev
• Sunon DR MagLev Motor Fan uses the MagLev technology with
new design features to increase dust-resistance and prevent oil
leakage.
• After 8 years of development and testing, Sunon’s DR MagLev
Motor Fan is being introduced in 2009 with four advantages:
- Better oil leak prevention
- Better dust-resistance
- Higher reliability
- Longer life expectancy

◎◎◎◎ Two innovative design concepts of DR MagLev development:
1. The B&S (Blanked & Seamless) Technology
2. The S&C (Seal & Clip) Design
◎◎◎◎ Three excellent efficiencies to extend fan life:
1. To avoid dust invasion and extend motor life
2. To prevent oil leakage
3. To prevent the motor components from falling off.

Note: DR MagLev Motor can be used with different motors types (radial, axial) and sizes,
so the final design may vary from the above, according to the different motor structures.

The S&C (Seal & Clip) Design can prevent the stator and impeller from falling off and help reduce noise that is caused by stator and impeller movement after a period of usage. The design greatly improves the life expectancy and the reliability.
Characteristic 3Characteristic 3::::::::High Reliability DesignHigh Reliability Design
The S&C (Seal & Clip) Design strengthens the locked position of both motor and stator to avoid stator and impellor from moving due to temperature changes. This allows the product to be more stable and run longer.

Better Life ExpectancyBetter Life Expectancy
Comparing the life expectancy of DR MagLev Motor design with other bearing systems, the life expectancy of the Precise VAPO bearing performs similar to 2 Ball bearing and therefore meets the customer’s requirements for continuous fan operation.

VAPO Bearing has lower acoustic noise than Ball BearingVAPO Bearing has lower acoustic noise than Ball Bearing
A test of continuous fan operation at a temperature of 70℃℃℃℃ shows that Ball bearing’s noise value will increase gradually over time while the noise value from the Precise VAPO bearing remains stable.
